![]() When you release the fish, it’s quite happy because is soft and doesn’t damage the fish. is almost transparent, very hard to see. The research group have developed several forms of these hydrogel robots, “ including a finlike structure that flaps back and forth, an articulated appendage that makes kicking motions, and a soft, hand-shaped robot that can squeeze and relax.” Researchers at Cornell have also developed their own hand-shaped soft robot recently, the GentleBot, which can feel external objects.Īssociate professor Zhao details its fish-catching capabilities, The clever aquatic robot was developed at MIT by graduate student Hyunwoo Yuk under the supervision of associate professor of mechanical engineering and civil and environmental engineering Xuanhe Zhao. ![]() Gif shows the soft robot catching and releasing a fish. Adding this to its transparency, the device is quite adept at sneakily capturing fish (as shown below). The substance is soft in nature and is therefore capable of grabbing objects like fish very delicately. The device is made out of transparent hydrogel material so the robot is almost entirely formed of water. These hollow structures inflate enabling the bots “ to curl up or stretch out.” This technique means the robot can expand and contract rapidly at a force of several newtons a second. In order to function, water is pumped into the robot’s 3D printed arms. The device can be likened to a claw crane, similar to the one used in construction or in arcade machines.

Recently MIT researchers published a study focusing on adapting 3D printed objects in the post-production phase and also evaluating how to 3D print with graphene.Įlsewhere in the field of soft robotics, Harvard recently used 3D printing to create their Octobot device which was hailed as the world’s first completely soft robot. Massachusetts Institute of Technology are known for their pioneering 3D printing research. The transparent gel robots can perform a number of tasks involving forceful movements such as a grabbing and releasing. In this review, we report the recent progress in the design and development of smart materials that are actuated by different stimuli and their exploitation within additive manufacturing to produce biomimetic structures with important repercussions in different but interrelated biomedical areas.Researchers at MIT have used 3D printing to create a new hydrogel device that can catch and release live fish. The term 4D printing was coined to indicate the combined use of additive manufacturing, smart materials, and careful design of appropriate geometries. In recent years, this issue has been addressed with the design and precise deployment of smart materials that can undergo a programmed morphing in response to a stimulus. However, an intrinsic limitation of this technology is that printed objects are static and thus inadequate to dynamically reshape when subjected to external stimuli. ![]() 3D printing technologies can recapitulate structural motifs present in natural materials, and efforts are currently being made on the technological side to improve printing resolution, shape fidelity, and printing speed. Nature's material systems during evolution have developed the ability to respond and adapt to environmental stimuli through the generation of complex structures capable of varying their functions across direction, distances and time.
